Hi,
There is nothing to worry as of now. Over dose of crocin is known to cause gastritis and
liver injury. Immediate vomiting after taking tablets will reduce the possibilities of these side effects.
As she doesn't have any symptoms right now there is nothing to worry. Ask her to take tablet Pantoprazole 40 mg once daily before food. This reduces gastritits.
If she develops pain abdomen, nausea please consult near by doctor.
Hope this helps.
